Fig. 1 show with cordless communication network 100 in the first node 110 that communicates of at least one Section Point 120.Communication between first node 110 and Section Point 120 can be undertaken by the communication carrier 140 in the community 150 that for example cordless communication network 100 comprises.Cordless communication network 100 can also comprise controls node 130.Controlling node 130 can be for example radio network controller.Controlling node 130 is the managent components in cordless communication network 100, can be responsible for control connection to the base station of controlling node 130 (as first node 110).Control node 130 and can realize RRM; Some mobile management function, and be to send to Section Point 120 and to receive from Section Point 120 position be encrypted user data.
In certain embodiments, first node 110 can be base station, wireless communications station, fixed station, control station, radio network controller, transponder or for any similar device of radio communication.In certain embodiments, Section Point 120 can be subscriber equipment, as maybe can the communicate by letter equipment of any other kind of Radio Resource of mobile cellular telephone, personal digital assistant (PDA), laptop computer, computer.
This method also can be used for the switching situation in cordless communication network 100.Switch call can have high priority.When operating in soft handover, mobile phone is connected to a plurality of communities simultaneously.Therefore, keep the channel in cell-of-origin, and the channel in cell-of-origin and parallel use a period of time of the channel in Target cell.In the situation that soft handover, before disconnecting with being connected of source, foundation is connected with target.Two connect the parallel time interval of using can be of short duration or long.Soft handover can relate to the connection of using with more than the Liang Ge community, and for example phone can keep with 3,4 or the connection of more communities simultaneously.When being called out under soft handover, at given time, for the signal of calling out optimum channel in the channel can utilize institute to use to some extent, or can be merged all signals, with the copy more clearly of generation signal.According to some embodiment, the latter may be more favourable.
Therefore, according to some embodiment, particularly when operating in when switching, Section Point 120 can be also base station, wireless communications station, fixed station, control station, radio network controller, transponder or for any similar device of radio communication.
Yet in the example depicted in fig. 1, first node 110 is base stations, Section Point 120 is mobile cellular telephones.
In addition, there is the advantage under TDD mode of working in (TDD) according to the cordless communication network 100 of this method and device.
The transfer resource at method scheduling first node 110 places in first node 110.As example, scheduling can occur in base station 110.According to some embodiment, scheduling can be partly in controlling node 130, partly carry out in base station.In certain embodiments, scheduling can be carried out fully in controlling node 130.
This method and device can be used in the wireless communication system 100 that comprises N carrier cell technology (as TD-SCDMA).
In N carrier wave TD-SCDMA system, ，Yi Ge community 150 can configure a plurality of carrier waves 140.If it is combinations of sharing the logic district 150 of identical common signal channel that each carrier wave 140 is counted as a logic district 150，Ze community 150.Therefore, can improve the service carrier capacity of system.The purpose of introducing the N ZAP is that this contributes to improved system for network capacity is provided.In theory, the capacity of N carrier wave TD-SCDMA system can be single-carrier system N doubly.
Therefore, can effectively distribute air interface resource.A plurality of frequencies in N carriers carry community 150.These carrier waves 140 in community 150 can be shared the common channel resources that is arranged in one of carrier wave 140.
Fig. 2 shows the resource location of the possible single downlink resource blocks that first node 110 and/or Section Point 120 use.In order to use coherent demodulation, for example frequency pilot sign 210 (being sometimes referred to as reference symbol or reference signal) for channel estimating is carried out to multiplexing transmission with data 220.As shown in Figure 2, Resource Block is expanded in time and frequency dimension.
Figure 3 illustrates the time dimension of the embodiment of possible TDD radio frames 310.Carrier wave 140 is divided into frame 310, and frame 310 is divided into time slot 320,340.
According to the radio frames 310 of illustrated embodiment, comprise: for example, connect 6 uplink resources (for example time slot 340) after 4 down-chain resources (time slot 320).Typically, resource can be time slot 320,340, but can also have other granularities according to some embodiment.Switching point 330 can be between downlink time slots 320 and uplink time slot 340.Time slot 320,340 can comprise reference symbol or pilot tone 360.
That Fig. 4 shows is that use by first node 110, for the basic principle of the method for distributing the resource in cordless communication network 100 multifrequency communities 150.This programme can comprise 3 kinds of algorithms: dynamic channel allocation (DCA) is received strategy 400, carrier wave priority algorithm 410 and time slot priority algorithm 420.Below will further explain the principle of these 3 kinds of algorithms, now focus on a kind of algorithm.
According to some embodiment of this method, according to the DCA of this programme, receive tactful 400 can be the algorithm at first called.Therefore, this method provides the set of scheme, so that higher priority service access to wireless communication system 100.The service of asking can be divided into 4 classes.According to the characteristic of asked service, they can be divided into: non-guarantee class comprises " interactive mode " and/or " background " service class.Equations of The Second Kind is to ensure class, comprises stream and/or speech business class.
The service of asking can also be asked because whether switching.Therefore, according to some embodiment of this method, DCA receives strategy 400 according to Types Below, all requests being divided into to following 4 kinds of service class: 1. non-guarantee/non-switching.In this case, service is non-guarantee, and does not have handover request.2. guarantee/non-switching.In this case, service ensures, and does not have handover request.3. non-guarantee/switching.In this case, service is non-guarantee, but has handover request.4. ensure/switching.In this case, service ensures, and has handover request.
In addition, according to this method, 3 threshold values have been introduced to control the access of many services.First threshold can be called as tdDcaTimeslotXThreshold, and wherein, X is number of timeslots, and scope is 0-6.Second Threshold can be called as tdDcaDINgThrh/tdDcaUINgThrh.The 3rd threshold value can be called as tdDcaDlgThrh/tdDcaUlgThrh.
Receive strategy 400 according to the DCA in up link and down link, for reserved some channel code resources of particular time-slot 320,340.In particular time-slot 320,340, when the sum of channel code resources surpasses first threshold tdDcaTimeslotXThreshold (wherein, X is the quantity of time slot 320,340, and scope is 0-6), block request.Can configure or measure based on Interference Signal Code Power (ISCP) value that first threshold tdDcaTimeslotXThreshold is set alternatively.ISCP is the measurement of disturbing in particular time-slot 320,340.This measurement has multiple application, as the user of time slot 320,340 and Channel Assignment to(for) wireless communication system 100.
In addition, according to this method, according to different COS, some channel code resources of all carrier waves 140 in reserved Yi Ge community 150.Surpass the set limit of Second Threshold tdDcaDINgThrh/tdDcaUINgThrh if be calculated as the expection number of codes of unavailability of the channel code of all carrier waves 140 or midamble code and the quantity sum of the code that distributes, block non-guarantee/non-handover request.
When the above-mentioned of the unavailability of the channel code that is calculated as all carrier waves 140 or midamble code with surpass the 3rd threshold value tdDcaDlgThrh/tdDcaUlgThrh, block non-guarantee/switching and guarantee/non-handover request.According to this rule, never block the guarantee/handover request according to this method.Therefore, the service that belongs to guarantee/switching class will be endowed priority, and suppose that the time slot 320,340 of discussing the reserved code in each except time slot 320,340 has enough code resources, the service that correspondingly belongs to guarantee/switching class will be accepted all the time.Do not comprise time slot 320,340 reserved code in each in Second Threshold tdDcaDINgThrh/tdDcaUINgThrh and/or the 3rd threshold value tdDcaDlgThrh/tdDcaUlgThrh.
In order to clarify and further illustrate this method, below example will be discussed.Yet, it should be noted, this is only non-limiting example, but not is intended to limit the scope of this method only limited by independent claims.
Yi Ge community 150 can only comprise a carrier wave 140, and wherein, the time slot configuration between up link and down link is 3: 3.Therefore, 3 time slots 320 are for up link, and 3 time slots 340 are for down link.In the TD-SCDMA system, can use 6 time slots 320,340 altogether in 1 carrier wave 140, each time slot 320,340 can carry 16 SF16 orthogonal codes, and wherein, SF (spreading factor) is 16.Can reserve 2 codes in each time slot 320,340, so tdDcaTimeslot1Threshold-tdDcaTimeslot6Threshold=2.Therefore, each time slot 320,340 only can be used 14 SF16 orthogonal codes.3 total total 143=42 codes of uplink time slot 320 are available.If Second Threshold tdDcaUINgThrh=14, the code that can be used for non-guarantee/non-switching is 42-14=28.When reaching this threshold level, will block non-guarantee/non-handover request.If the 3rd threshold value tdDcaUlgThrh=6, the code that can be used for guarantee/non-switching and non-guarantee/switching is 42-6=36.
Non-guarantee/non-handed over service will get clogged all the time.When the up link code of community has been consumed 36 SF16 channel codes, will block guarantee/non-switching and non-guarantee/handed over service.
According to this method, for guarantee/handed over service, must meet reserved 2 SF16 channel codes in each time slot 320,340.
If community 150 only comprises a carrier wave 140, priority value is unnecessary, and, according to this method, can call time slot priority algorithm 420 with direct assigned code.
Yet, in order for example to support the N carrier wave, can in community 150, configure the carrier wave more than.Can in community 150, configure an only main carrier 140.In addition, according to some embodiment, can in community 150, configure 0-5 auxiliary carrier wave.
Therefore, when will be for the special services Resources allocation, for following carrier wave priority algorithm 410, priority sequence that must all candidate carrier of definition.
Each carrier wave can be by for example controlling node 130 imparting system priority.Priority limit from 1 to 6, wherein, the 1st, highest.Priority value can be predefined, the configuration or according to some embodiment tuning dynamically arranging Network Based.Priority based on carrier wave in community 150, at first consider that load can meet the limit priority carrier wave 140 of service request.
If community 150 comprises the carrier wave more than, these carrier waves will be divided into two sections: voice preference carrier wave section and data, services preference carrier wave section.Can configure or the tuning number of carriers dynamically arranged for every section division Network Based.Ratio can depend on for example business model.
When according to this programme, being services selection carrier wave 140, must calculate except all residue codes in all uplink/downlink time slots 320,340 in Ma Wai community 150 of reserving in each time slot 320,340 for all carrier waves.
According to some embodiment of this method, can calculate each time slot load 320,340 in the total load of each carrier wave in uplink/downlink and uplink/downlink.If the institute in carrier wave 140 withs a hook at the end, reserved code, in carrier wave 140, all codes of uplink/downlink, more than the demand code, can be selected carrier wave 140.
For current service, can select all available carrier wave by same procedure, and can only select up link and down link condition to meet those carrier waves of current service simultaneously.
The priority configuration of all candidate carrier can configure based on carrier system.As previously mentioned, all unavailable carrier waves have been assigned from high to low.In addition, all unavailable carrier waves are to be configured in a section in two sections (segment of speech and/or data, services sections).If all carrier waves have some different priorities, limit priority carrier wave 140 will be configured in the front end of arrangement.Therefore, at first the carrier wave 140 of limit priority will be considered to have.
If exist have same systems priority more than a carrier wave 140, for the independently service of 3.4kbps signaling/CS speech (12.2kbps), at first the carrier wave in the voice preference section is put into to the candidate and arranged, and can give higher priority to one that there is low load in them.Then, the carrier wave in data, services preference section can be put into to the candidate and arrange, and compare with the carrier wave that hangs down load in data, services preference section, can give higher priority to the carrier wave 140 with higher load.
For other services, at first the carrier wave in data, services preference section is put into to arrangement, and higher load will have higher priority; Then, in turn, with the carrier wave in the voice preference section, compare, to thering is the assignment of carriers higher priority of low load in the voice preference section.
Adopt and can give mode like priority class for carrier wave according to carrier wave priority algorithm 410, can be each time slot 320,340 configuration-system priority in uplink/downlink.After having selected a carrier wave 140, time slot 320,340 is selected in the time slot priority based in up link and down link and time slot load respectively.Can only select load to meet those time slots 320,340 of service request.
When candidate carrier configures in priority sequence, can distribute suitable time slot 320,340 and code according to time slot priority algorithm 420.Now, can carry out time slot 320,340 and code distribution trial to a carrier wave, distribute and attempt originating in the limit priority carrier wave until the lowest priority carrier wave can meet suitable carrier wave 140 service request, that have suitable time slot 320,340 and code until find.
For the ease of reader understanding's this method of knowledge shortcoming, can give the non-limiting example of the function of output time slot priority algorithm 420.This example relates to the community 150 that comprises 3 carrier waves.After at first having carried out carrier wave priority algorithm 410, elect the second carrier wave and the 3rd carrier wave as candidate carrier, and it is put into to priority query in order.Then, will distribute time slot 320,340 and code.At first, the time slot in first carrier and code in priority query will be attempted distributing.If attempt unsuccessfully, in priority query, in next carrier wave 140 grade, newly attempt.Once can become distribution of work time slot 320,340 and code, just can call and receive control 400 whether available to judge the power related resource.
